Great cards to tinker with! These are Barco MXRT 7500s, based on the FirePro W7000, this is a GCN card similar to the HD 7870 but with a lower TDP and more VRAM. In order to use it for gaming with R.ID or Radeon drivers, you have to have some knowledge or willingness to learn about flashing a BIOS on the card. It's not something I want to put the time into, but it is well documented.
